You can't have tried too many programs, or the file must be completely fubar. I suspect the former.

VLC - if it can play it, it can transcode it.
Xvid4PSP
Any Video Converter Free
AVI Demux should be able to demux the audio, and the latest Audacity beta with ffmpeg should be able to load and convert the results

Avanti (w/ffmpeg) will extract/convert the AAC audio fine. That's what I use.

Best,

Thanks for the help Guns1inger and Calidore, but the programs that you mentioned seemed to have a problem with the audio
But I was able to encode the audio with TMPGenc Xpress and it worked fine!

[Calidore]

Glad to hear you got it working!

Best,
